Valve actuators chosen for water treatment

Edited by the Engineeringtalk editorial team Oct 5, 2007

44 Rotork double-acting, scotch-yoke pneumatic actuators have been installed throughout the two project stages of the Los Horcones water treatment plant.

Rotork fluid power valve actuators have been installed throughout a major new water treatment plant which supplies up to 500 litres of drinking water per second to the city and port of Mazatlan in the Mexican state of Sinaloa.

A total of 144 Rotork double-acting, scotch-yoke pneumatic actuators have been installed throughout the two project stages of the Los Horcones water treatment plant, which began operating in May 2007.

The actuators, from Rotork Fluid Systems' CP and P ranges, operate butterfly valves in sizes from 152 to 508mm.

All the actuators are equipped with DynaTorque manual overrides.

Built for the Mexican water authority Jumapan, the Los Horcones plant treats water from two inland wells in order to remove iron and manganese.

The US $11.6 million plant has been constructed by Constructora y Cribados Almoza.

The orders for the actuators were won by Rotork's representative in the country, Rotork Servo Controles de Mexico.
